One Web Mode The way the sensor works can also be changed with the
One
Web Mode
parameter. It can be turned on or off.
One Web Mode:
OFF Parameter
One Web Mode
is turned off.
– If there is no suitable contrast value, it is assumed that the
corresponding material edge is outside the sensor field of
view.

See
Figure 1.2
for 8 different cases a to h
– The corresponding extreme value of its signal range x
i
or x
o
is assigned to the relevant output functions.

x
i
= 0 or 4mA and x
o
= 10 or 20mA with normal output
functions and vice versa for the inverted output functions.
One Web Mode:
ON Parameter
One Web Mode
is turned on.
This parameter setting is intended for materials with unevenly
distributed material thickness (cloudy) in which edges may
incorrectly be detected in the middle of the material web.
The position of the positive contrast with the smallest distance
from the closed end of the sensor is assigned to the output
function "Edge 1." Of the two negative contrasts, the position of
the contrast with the greatest distance from "Edge1" is assigned
to output function "Edge 2." The two remaining contrasts are
not used for any further purposes.
Edges 1 to 4 are identified by E1 to E4.
